NVD Description

Note: Versions mentioned in the description apply only to the upstream satellite/foreman-mcp-server-rhel9 package and not the satellite/foreman-mcp-server-rhel9 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.1, Authlib's OctKey.import_key() and HMAC signing and verification path accept zero-length key material. If an application's secret lookup can return an empty string or empty bytes, a remote attacker can compute the deterministic HS256, HS384, or HS512 signature for arbitrary token claims and have Authlib treat the token as authentic. This issue is fixed in version 1.9.1.
